CONTROL PACKER HEAD.

, Application filed December 18, 1924. Serial No. 756,704.

To all whom t may concern:

Be it known that we, CHARLES M. Human and J osnrrry W. HEETER, both citizens of the United States, residing, respectively, at Butler, county of Butler, and State of Pennsylrsiinia, have invented a newv and useful Improvement in Control `Packer Heads, of which the following isi a full, clear, and "Xac-t description.

The present invention lrelates broadly to oil well equipment, and more particularly to a packer head by means of whichy oil flowing from av well can be collected and saved during' the setting of the tubing. Y

At the present time it is customary in the art to which the present invention relates, after a hole-has been drilled to the desired depth, to lower into the hole an anchor carrying a packer adapted to be expanded against the walls of the hole. The anchor maybe of any'desired'length, whereby the packer will be 'supported at the required distance above the bottom vof the well. The present invention relates to adevice adapted to be secured above the packer for receiving the oil and delivering it around the tubing, whereby it may be recovered nby means of a flow catcher, as well understood in the art.

vIn the accompanying drawings, there is shown for purposes of illustration only, a preferred embodiment of the present invention, it being understood that the drawings do not define the limitsof theinvention and that changes in the construction therein disclosed may be made without departing from the spirit of the invention or. the'scope of our broader claims.

In the drawings: j

Figurel isa side elevation of the packer head, the parts being shown in extended relation; Y l

'Figure 2 is a view 'similar kto VFigure 1', showing the parts in telescoped relation; and' Figure 3 is a vertical sectional view, illustrating the parts in an intermediate position.

A packer head constructed 'in accordance with the present invention preferably comprises a sleeve 2 having its lower end threaded to receive a coupling 3, which is in turn threaded to cooperate with a tube or pipe section 4 which may extend downwardly to or comprise part of a packer of any desired construction.

The opposite end of the sleeve 2 is shaped to provide a projecting shoulder or bead 5 adapted to cooperate with a collar 6 which is placed over the sleeve before the coupling 8 is secured in position. The collar G has a threaded portion 7 of reduced diameter adapted to receive the lower end of a casing 8 of a diameter such that it may easily slide over the sleeve 2. The upper end of the casing 8 is reduced and provided with a threaded portion 9 adapted to receive a coupling 10 which at its opposite end is threaded onto the iiow pipe 11.

Theupper surface of the coupling 3 is provided with a groove 12 having a packing 12 and the lower end of the collar 6 is provided with a projection 413 adapted to form a tight fit with this groove and packing when the parts are in telescoped position, as indicated in Figure 2.

The sleeve 2 is provided with one or more openings 14C, preferably of elongated form, adapted to permit any fluid which iiows upwardly through the coupling 3 and sleeve,

as indicated by the arrow A, to flow outwardly around the sleeve land casing 8, as indicated by the arrows B during the time the anchor, the packer and the packer head with its connected piping are being lowered into the well. During this lowering movement the parts are held in extended relation by means of a'frangible rivet or bolt 15. During this time also iiow through the casing is prevented by a frangible disk 16 which may be 4of babbitt,-cast iron or other metal suitably positioned within the coupling 10` and completely closing its How opening. VThe under side of this disk is provided with a recess or pocket 17 cooperating with the upper end of a breaker rod 18 having va shoulder 19 at its lower end and a projection 20. The shoulder 19 engages the lower end of one of the openings 14; and the projection 20 is riveted or otherwise secured to the sleeve by a frangible connection 21. The side of the rod is formed with an inclinedsurface 22 adapted to project outwardly through the opening 14 in such manner as to be engaged by the collar 6 during the telescoping movement ot the parts. rlfhis movement will be eilective for shearing the connection 21 and pushing` the rod 18 inwardly toward the center ot the sleeve, whereby the inclined portion 23 or the shoulder 19 will be brought into Contact with the bottom of the opening 14 to permit the rod to drop out otl the opening and on downwardly through the sleeve, packer and anchor.

During the lowering of the entire assembly into a well, the parts will all move in unison until the anchor reaches the bottom oi the well. Thereafter the packer will set, checking the 'further movement ot the parts and resulting in the shearing oit the pin 15. The sleeve and casing at this time will conimence telescoping, such movement being prevented only by the rod 18 and disk 1G. Due to the irangi'ble nature of the disk 1G, it will be broken to establish a flow opening through the coupling 10 and the pipe 11. Continued telescoping of the parts will bring the-collar (3 into engagement with the lower end of tle rod 1S, resulting in displacing the same and permitting it to fall to the bottom ot the well, as before pointed out. Final movement of the parts will bring the lower end of the collar into sealing relationship with the couplingl 3 to prevent any further How of fluid outwardly through the openings 14, and causing all ot the fluid to pass axially through the control packer head into the piping 1'1.

It will be understood that during the lowering of the parts into the well the oil which flows upwardly around the piping 11 can be recovered by any well known foi-moic flow catcher located at the top of the well.

The advantages of 'the present invention ari g. from the provision of a packer head adapted to be lowered into a well with the e'wling for initially del'lecting oil outwardly around the. piping and 'for later cutting oil auch iiow oit oil and establishing the desired flow through the piping.
